Minimal exercise, maximum benefit? Comparing incidental physical activity with structured exercise participation on three measures of well-being in a group of corporate employees
In response to increasingly sedentary workplaces, many organizations utilise employee well-being programmes that include physical activity. Physical activity is purported to have physiological benefits and improve overall mental well-being and is assumed will benefit the organization through reduced absenteeism rates and enhanced job satisfaction. Whilst research found associations between engagement in exercise and increased levels of well-being, conflicting support exists for reduced absenteeism and little support was found for enhanced job satisfaction. Much research has also failed to consider any mediating effects that stress may have had on the outcome. In addition, there exists little research that compared the effects of general physical activity with structured exercise participation on reports of well-being, which may be of use for wellbeing programme policy. This paper will review the literature regarding exercise and physical activity and the effects on factors of subjective well-being, job satisfaction and stress. Weaknesses as well as strengths in the body of knowledge will be reviewed, it will be suggested that it is timely and important to further investigations in this area. Objectives: Whilst the world health organisation (WHO) asserts that western societies show insufficient levels of physical activity (PA), research has paid little attention to the contribution of non regimented activities to well-being. The current study compared global well-being (GWB), job satisfaction (JS) and perceived stress (PS) between corporate employees who engage in sport and those, less active, whose PA is intertwined in their daily routine. Four predictions were tested. Firstly, the sport group would report significantly higher GWB. Secondly, there would be a significant positive correlation between PA and GWB. Thirdly, there would be a significant negative correlation between PS and PA levels. Fourthly, there would be a significant negative correlation between PS and JS. Design: Cross sectional survey Methods: Participants were 216 corporate employees (n =162 females & n =54 males). They completed sport and leisure indexes of a sport questionnaire. GWB was assessed with the satisfaction with life scale, JS with a job satisfaction scale, and PS using a four item perceived stress scale. Data analysis comprised two MANOVAs and bivariate correlations. Results: The first hypothesis was not supported as the leisure group reported a statistically higher level of GWB. Hypotheses two and three were both supported. Hypothesis four was not supported as a non significant negative correlation was found. Conclusion: The findings suggest that whilst physical activity overall does contribute to enhanced GWB and reduced PS, the activities are optimally rewarding when incorporated into daily routine. JS, however, was significantly higher for the sport group
Turning Point: The 2016 Salukis
An ABSTRACT OF THE THESIS OF

TITLE: TURNING POINT: THE 2016 SALUKIS
MAJOR PROFESSOR: JAN THOMPSON
The purpose of this project was to document the journey of a football team through fall practice, but as camp ended it was clear the story was still unfolding. As a result, Turning Point follows the team through an entire season. Turning Point was borne because of a graduate student’s exposure to video services and athletics. During the assignment, it became apparent that following the team would make a great story. The graduate student status provided unfettered access to the SIU sports teams and promised insight for both the reader and the researcher. The football team was and still is going through an image change with a new head coach and staff and thus a renaissance in the culture of the program. Capturing that process on film will hopefully fill a gap in the research for football teams, coaches, and filmmakers. There are out takes of the players, coaches in meeting, practices and game day activities. The footage within Turning Point contains scenes that most are not privileged to as an average fan. Turning Point was designed to tell the story off the field to supplement and help tell the story on the field. Seeing what the players and coaches go through on a day to day basis invests the viewer into being much more than a fan, making the viewer a part of the reverence of what Saluki football truly is. The complexity of this team and the multiple story lines presented made this team the perfect final test for a thesis and the project tested all of the researcher’s skills to document a diverse and compelling story
Macrofossils and pollen representing forests of the pre-Taupo volcanic eruption (c. 1850 yr BP) era at Pureora and Benneydale, central North Island, New Zealand.
Micro- and macrofossil data from the remains of forests overwhelmed and buried at Pureora and Benneydale during the Taupo eruption (c. 1850 conventional radiocarbon yr BP) were compared. Classification of relative abundance data separated the techniques, rather than the locations, because the two primary clusters comprised pollen and litter/wood. This indicates that the pollen:litter/wood within-site comparisons (Pureora and Benneydale are 20 km apart) are not reliable. Plant macrofossils represented mainly local vegetation, while pollen assemblages represented a combination of local and regional vegetation. However, using ranked abundance and presence/absence data, both macrofossils and pollen at Pureora and Benneydale indicated conifer/broadleaved forest, of similar forest type and species composition at each site. This suggests that the forests destroyed by the eruption were typical of mid-altitude west Taupo forests, and that either data set (pollen or macrofossils) would have been adequate for regional forest interpretation.
The representation of c. 1850 yr BP pollen from the known buried forest taxa was generally consistent with trends determined by modern comparisons between pollen and their source vegetation, but with a few exceptions.
A pollen profile from between the Mamaku Tephra (c. 7250 yr BP) and the Taupo Ignimbrite indicated that the Benneydale forest had been markedly different in species dominance compared with the forest that was destroyed during the Taupo eruption. These differences probably reflect changes in drainage, and improvements in climate and/or soil fertility over the middle Holocene
Late Holocene palynology and palaeovegetation of tephra-bearing mires at Papamoa and Waihi Beach, western Bay of Plenty, North Island, New Zealand.
The vegetation history of two mires associated with Holocene dunes near the western Bay of Plenty coast, North Island, New Zealand, is deduced from pollen analysis of two cores. Correlation of airfall tephra layers in the peats, and radiocarbon dates, indicate that the mires at Papamoa and Waihi Beach are c. 4600 and c. 2900 conventional radiocarbon years old, respectively. Tephras used to constrain the chronology of the pollen record include Rotomahana (1886 AD), Kaharoa (700 yr B.P.), Taupo (Unit Y; 1850 yr B.P.), Whakaipo (Unit V; 2700 yr B.P.), Stent (Unit Q; 4000 yr B.P.), Hinemaiaia (Unit K; 4600 yr B.P.), and reworked Whakatane (c. 4800 yr B.P.) at Papamoa, and Kaharoa and Taupo at Waihi Beach. Peat accumulation rates at Papamoa from 4600 - 1850 yr B.P. range from 0.94 to 2.64 mm/yr (mean 1.37 mm/yr). At Waihi Beach, from 2900 yr B.P. - present day, they range from 0.11 to 0.21 mm/yr (mean 0.20 mm/yr). Peat accumulation at both sites was slowest from 1850 to 700 yr B.P., suggesting a drier overall climate during this interval. At both sites, the earliest organic sediments, which are underlain by marine or estuarine sands, yield pollen spectra indicating salt marsh or estuarine environments. Coastal vegetation communities declined at both sites, as sea level gradually fell or the coast prograded, and were eventually superseded by a low moor bog at Papamoa, and a mesotrophic swamp forest at Waihi Beach. These differences, and the marked variation in peat accumulation rates, probably reflect local hydrology and are unlikely to have been climatically controlled. The main regional vegetation during this period was mixed northern conifer-angiosperm forest. Kauri (Agathis australis) formed a minor component of these forests, but populations of this tree have apparently not expanded during the late Holocene at these sites, which are near its present southern limit. Occasional shortlived forest disturbances are detectable in these records, in particular immediately following the deposition of Taupo Tephra. However, evidence for forest clearance during the human era is blurred by the downward dislocation of modern adventi ve pollen at these sites, preventing the clear differentiation of the Polynesian and European eras
NASA Desert RATS 2011 Education Pilot Project and Classroom Activities
The National Aeronautics and Space Administration's (NASA's) Desert Research and Technology Studies (Desert RATS) is a multi-year series of tests of hardware and operations carried out annually in the high desert of Arizona, as an analog to future exploration activities beyond low Earth orbit [1]. For the past several years, these tests have occurred in the San Francisco Volcanic Field, north of Flagstaff. For the 2011 Desert RATS season, the Exploration Systems Mission Directorate (ESMD) at NASA headquarters provided support to develop an education pilot project that would include student activities to parallel the Desert RATS mission planning and exploration activities in the classroom, and educator training sessions. The development of the pilot project was a joint effort between the NASA Johnson Space Center (JSC) Astromaterials Research and Exploration Science (ARES) Directorate and the Aerospace Education Services Project (AESP), managed at Penn State University
Effectiveness of a social support intervention on infant feeding practices : randomised controlled trial
Background: To assess whether monthly home visits from trained volunteers could improve infant feeding practices at age 12 months, a randomised controlled trial was carried out in two disadvantaged inner city London boroughs.
Methods: Women attending baby clinics with their infants (312) were randomised to receive monthly home visits from trained volunteers over a 9-month period (intervention group) or standard professional care only (control group). The primary outcome was vitamin C intakes from fruit. Secondary outcomes included selected macro and micro-nutrients, infant feeding habits, supine length and weight. Data were collected at baseline when infants were aged approximately 10 weeks, and subsequently when the child was 12 and 18 months old.
Results: Two-hundred and twelve women (68%) completed the trial. At both follow-up points no significant differences were found between the groups for vitamin C intakes from fruit or other nutrients. At first follow-up, however, infants in the intervention group were significantly less likely to be given goats’ or soya milks, and were more likely to have three solid meals per day. At the second follow-up, intervention group children were significantly less likely to be still using a bottle. At both follow-up points, intervention group children also consumed significantly more specific fruit and vegetables.
Conclusions: Home visits from trained volunteers had no significant effect on nutrient intakes but did promote some other recommended infant feeding practices
